Rauen, 172 Woodlawn Lane, Oconomowoc, Wis. Filed Dec. 31, 1956, Ser. No. 631,571 Claims. (Cl. 50-226) This invention relates to metal siding with integral nailing tabs.

Each siding strip has its upper margin turned downwardly and slightly outwardly and thence formed inwardly upon itself in a fold which provides a continuous seal in engagement with an inwardly and upwardly folded flange on the next higher piece of siding. It is desirable that the extreme edge of the upwardly extending portion of the flange of the higher strip be engaged in the bight of the downwardly turned top margin of the first mentioned piece of siding, and that the margin of the strip formed inwardly upon itself shall engage a channel provided in the outer surface of the flange along the bottom edge of the next higher piece of siding.

In order to achieve these objectives, while at the same time providing for connection with each piece of siding along its upper edge to the building wall upon which it is mounted, I provide tabs cut from the downwardly and outwardly turned portions of each piece of siding, which tabs are allowed to extend upwardly in order that tabs at any desired spacing may be used for nailing purposes, the sealing fold being complete and unbroken beneath the apertures from which the tabs are struck.

In the drawings:

FIG. 1 is a view in vertical transverse section through successive pieces of siding as applied to a building wall diagrammatically shown.

FIG. 2 is a fragmentary detail view in perspective showing an end portion of a piece of siding on a reduced scale.

FIG. 3 is a fragmentary detail view of the lower portion of a piece of siding as it appears in end elevation.

The building wall 5 may be of any desired construction. Each piece of siding comprises a panel 6 provided at its upper margin with a series of tabs 7 held to the wall by nails or the like at 8. From the tabs, the panel 6 diverges downwardly and outwardly from the wall, being held away from the wall at its lower end by a flange 9, bent cylindrically at 10 and having its free margin 11 extending upwardly. The cylindrical bend at 10 provides an outwardly opening channel at 12. As best shown in FIG. 3, the marginal portion at 11 of the siding flange 9 is initially approximately parallel with the panel 6.

At its upper margin, the siding has a fold at 13 from which the metal extends outwardly at 14, its extreme margin 15 being bent inwardly and upwardly upon the seal fold 16. After each piece of siding has been nailed to the wall, the next higher piece has its terminal flange 11 manipulated between the margin 15 and the panel of the lower length of siding until the margin 15 is engaged in channel 12 and the seal fold 16 contacts the lower flange 9 as clearly shown in FIG. 1. This deflects flange 11 somewhat from the position in which the flange is illustrated in FIGS. 2 and 3. The bias of the material which results from this deflection maintains the parts snugly in assembly.

The several tabs 7 are cut from the material of the downwardly folded portion 14 of the siding, leaving openings at 18, all of which are disposed above the sea-ling fold 16, whereby the sealed connection between the fold 16 and the top or inner surface of flange 9 of two consecutive pieces of siding is continuous and unbroken and has much greater strength than would be the case if the openings 18 intersected fold 16.

The resulting wall is given an appearance closely comparable to that which would be achieved through the Patented July 11, 1961 use of wooden siding, the flange 9 and panel 6 appear- The rigidity and strength and freedom from vibration achieved by reason of this construction are much superior to other metal siding.

It will be understood that the provision of the nail-receiving apertures 19 in tabs 7 is optional and the person erecting the siding is able, because of the large number of the tabs, to locate the supporting nails at any desired spacing. Ordinarily, nails will connect the tabs to the building only at points where the nails can enter the studs or other structural members. The large number of tabs, most of which are unused in practice, and the rounded form thereof, give the unmounted siding a unique and distinctive and attractive appearance which contributes to sales appeal.

I claim:

1. A strip of metal siding having both longitudinal edges thereof continuous and adapted for bearing engagement of the edges on adjoining strips of siding and providing a cylindrical sealing surface between the bottom of one strip and the top of a like lower strip, and comprising a panel having a bent upper margin providing an outwardly and downwardly extending first portion with integral nailing tabs projecting upwardly and struck from said first portion leaving openings wholly within said first portion, said panel further having a second portion extending inwardly from said first portion and providing a continuous edge adjacent the panel and said panel further having a bent lower margin providing a flange with a first inwardly extending portion and a second portion extending thence upwardly, said flange having a channel presenting a convex face adapted to seat against the face of a like siding strip beneath the said first upper portion of said like siding strip, the channel of the said lower flange being adapted to receive the inwardly extending portion of such like strip, whereby a seal is provided substantially throughout the length of adjacent siding strips.

2. The siding of claim 1 in which said first upper portion is disposed at an angle to the panel and said second upper portion extends substantially perpendicularly to the panel for bearing in the channel of a like strip along the entire length thereof while said lower first portion extends substantially perpendicular to the panel and said lower second portion is initially substantially parallel to the panel and is bent outward by said first upper portion upon seating therein of the said lower second portion.

3. The siding of claim 1 in which the nailing tabs are spaced by approximately the width of a tab along the entire length of a strip.

4. A strip of metal siding comprising a panel portion, an upper marginal portion integral with the panel portion and extending outwardly and downwardly from the panel portion and having an unbroken bend inwardly along its lower margin, a series of longitudinally spaced nailing tabs projecting upwardly and integral with the panel portion and struck from said upper marginal portion, the said upper marginal portion having openings from which the tongues are struck and below which the said unbroken bend is continuous, and a lower marginal portion integral with said panel portion and projecting inwardly beneath the panel portion and having a marginal flange projecting upwardly.

5. A siding strip in accordance with claim 4 which is adapted for assembly with a like strip, the marginal flange projecting upwardly from the lower marginal portion of the strip as aforesaid in claim 4 being receivable between the panel portion and the inward bend of the upper marginal portion of a like strip and having a longitudinal channel in which said inward bend of said like strip is receivable to provide a continuous seal.
